Exactly where do I need to go to look at this and what exactly am I looking for?'
I think I found the eq graphs at auto setup-> parameter check-> room eq or something along those lines.
I am not sure if this is what you are talking about, or what to look for from here.
The audyssey EQ curve shows a steep drop that looks like an upside down triangle from about 40 hz to 100 hz for the L/R mains. The peak of the triangle goes down to about -18db.
